Question for all the torque wrench users, How often do you have your wrenches checked for calibration? Continue at your own risk.......
Testing torque wrenches used in a manufacturing facility was part of my old job for about 15 years, Around 300 of them and all different brands and types. A personal observation from doing thousands of tests on a half dozen or so different brands used in an industrial environment: If you have an older Proto, MAC or US made Craftsman and don't substitute your torque wrench for a breaker bar or hammer you're probably fine for a few decades. If you have a Snap On get it checked occasionally. If you have a cheap Chinese wrench you really don't want to know........ Of all the brand name consumer grade wrenches the company used Snap On were the only ones we had to remove from service for being out of calibration and it was usually within a year to 18 months. Snap On doesn't warranty tools used in a manufacturing facility either. To save money they tried buying the Chinese cheapies through McMaster-Carr and Grainger. Those had an 80% failure rate right out of the package and the few that passed the first time rarely made it past 6 months at which point the ratchet heads were usually slipping anyway. The best were the industrial grade wrenches from Beloit, Belknap and anything with Sturtevant and/or Richmont as part of the name but they are $$$ so it's doubtful too many home shops will have those. Kudos to anyone that does have any though, GOOD STUFF!
